CHARLOTTE, N.C. -- The state released Friday the autopsy and toxicology reports of a man killed by a Charlotte police officer in early September.

The reports, obtained by WBTV, confirm Jonathan Ferrell died from multiple gunshot wounds to his chest. The toxicology report says he had caffeine, nicotine and ethanol in his system.

Officer Randall Kerrick shot Ferrell 10 times, according to WBTV. He is charged with Voluntary Manslaughter and is on paid leave during the investigation.

The officers gave several verbal commands to 'get on the ground, get on the ground', at least three commands," George Laughrun, Kerrick's attorney, told WBTV. "He continued approaching the officers, advancing toward them."

Chris Chestnut, the Ferrell family attorney, told WBTV, "[Kerrick] knew what he was doing. He shot, paused, shot again. Paused, shot again -- he killed."

Chestnut also emphasized to WBTV that Ferrell was outnumbered by officers three to one. "These are trained officers, trained in defensive tactics. Three to one, no need to shoot," he said.
